Take the motor mounts out with it complete-
3x 15mm or 17mm nuts per side, up in the front crossmember.
Drop the trans crossmember, the driveshaft, and the shift linkage, and take the engine and trans together. It'll be easier, trust me. Oh yeah, trans cooler lines to the radiator too.

Drop the exhaust off it complete at the manifold, 8x 13mm nuts at the head. Be careful not to break any studs, cut off or chisel any stuck exhaust nuts.

You won't need to remove the hood, the radiator support, or the AC condensor. The radiator comes out easily to get access. You could leave the intake in the car if you want. Unhook everything and it can flop out of the way. You can either take the engine harness with it or pull it ALL off, which means pulling the little clamps under the front pulley, the ignition harness, and the alternator wiring too.

Pull your dipsticks out too, they're likely to get broken as the engine comes out- it wants to twist around and fall over. You can hook it using the factory hooks at the thermostat and back of the intake- they're pretty strong surprisingly.

If you don't need the accessories like the AC, power steering pump, and alternator, you can remove them and avoid disconnecting things like AC hoses. That big one across the top, you're not going to avoid, unless you're very fancy with positioning things. Probably need to accept that you're venting the AC on both car's systems. That's probably illegal where you are, unless you have an EPA license for AC- so be advised.

Good luck with the job. Did this last year, putting an 89 240 engine into a, 88 740 sedan. The memories are still fresh...
